Here's another thought. I think most of us would agree that we bring home much more than we take down with us. In order to keep a nice balance, I try to bring down "half empties". Instead of buying things like shampoo, conditioner, soap, toothpaste, etc. just for the trip, I bring down the partially used toiletries I have and just throw away whatever is not used. The travel sizes just aren't big enough for a week at Disney.
